SARS-Cov-2 is a corona virus that causes COVID-19 disease, a viral infection responsible for the pandemic decreed by the World Health Organization in March 2020. Angiotensin-converting enzyme 2 (ACE-2) functions as the main receptor for SARS-Cov-2. The study aimed to detect the expression of ACE-2 in the gastrointestinal tract, kidney, and lung in the rhesus monkeys and squirrel monkeys.

Campylobacter infections are a prevalent cause of diarrheal disease in humans and are the most significant zoonotic pathogens worldwide. Human campylobacteriosis is generally via ingestion of contaminated poultry products. However, based on recent studies chicken egg yolk antibody (IgY) powder has great potential to reduce the cecum load of Campylobacter jejuni (C.

Background: Simulated microgravity environment can lead to gastrointestinal motility disturbance. The pathogenesis of gastrointestinal motility disorders is closely related to the stem cell factor (SCF)/c-kit signaling pathway associated with intestinal flora and Cajal stromal cells. Moreover, intestinal flora can also affect the regulation of SCF/c-kit signaling pathway, thus affecting the expression of Cajal stromal cells.

Inflammatory bowel disease is triggered by abnormalities in epithelial barrier function and immunological responses, although its pathogenesis is poorly understood. The dextran sodium sulphate (DSS)-induced colitis model has been used to examine inflammation in the colon. Damage to mucosa primality occurs in the large intestine and scarcely in the small intestine.

Chondroitin sulfate (CS) and glucosamine (GlcN) are indicated for the treatment of some inflammatory diseases, such as osteoarthritis, mainly because of the anti-inflammatory effects in reducing metalloproteinases activities (MMP), and other inflammatory mediators. Herein, we reported the structure of the CS, the anti-inflammatory and protective effects of the CS, and GlcN administration in ulcerative colitis model induced by dextran sulfate sodium (DSS) in rats. Experimental data indicated that CS disaccharide composition is very similar to the C4S standard, with modal molecular weight at 30.
